Case Study: Regional Health Company achieves 22% reduction in ER use and boosts member engagement with Castlight Health

A health plans journey to increasing satisfaction and reducing costs

A regional health plan offering a wide range of employer-sponsored benefits struggled to drive engagement—fewer than 10% of members used the full suite of services—and faced a confusing benefits structure, limited population-level reporting, and pressure to reduce total cost of care, aid client talent retention, and stay competitive in the market.

Partnering with Castlight, the plan launched a single digital “front door” that uses claims, gaps-in-care, provider quality and price data to deliver personalized recommendations, timely nudges, and population health analytics. One year post-launch registered members were 50% likely to search for care (2023), showed a 22% reduction in ER utilization versus non-registered members, and were roughly twice as likely to engage in primary and preventive care—driving improved care utilization, cost outcomes, and positive employer/broker feedback.
